WHAT IS NFC?

Wireless communication technology

Enables data transfer between machines

Uses the concept of Radio Frequency Identification (RFID)

IN SIMPLE WORDS…

A WAY BY WHICH DEVICES CAN SEND

AND RECEIVE INFORMATION

WIRELESSLY AT A CLOSE RANGE

HOW IT WORKS?

NFC works:

Via magnetic field induction technology, and

operates on an unlicensed radio frequency band

Works within a range of 10 cm or less and supports encryption

Requires low power to run

Compatible with contactless Radio Frequency Identification

MODES OF OPERATION

MODES OF OPERATION

ACTIVE MODE

PASSIVE MODE

Active mode-

Two NFC enabled devices transferring data in active mode

Inducing magnetic field

MODES OF OPERATION

Passive mode-

A NFC-enabled mobile phone is paired with a RFID-tagged "smart poster"

APPLICATION OF NFC

NFC APPLICATIONS

TOUCH AND GO

TOUCH AND CONFIRM

TOUCH AND CONNECT

TYPES OF NFCAPPLICATIONS

• Application such as access control or transport/event ticketing , where the user only needs to bring the device storing the ticket or access code close to the reader

TOUCH AND GO

• Application such as mobile payment where the user has to confirm the interaction by entering a password or just accepting the transaction

TOUCH AND CONFIRM

• Links two NFC-enabled devices to enable transfer of data amongst them, such as downloading music, exchanging images etc.

TOUCH AND CONNECT

CARRY YOUR WORLD AROUND

ADVANTAGES OF NFCHigh convenience to the user, because

the data exchange is done just by bringing two mobiles together.

Secure communication.

No special software.

No manual configuration and settings.

No search and pair procedure.

NFC can be used together with existing technologies like Bluetooth and thus act for longer range also.

DISADVANTAGES OF NFC

The system has the limitation that it can be operated only with devices under a short range i.e. around 10 cm.

The data transfer rate is very less at about 106kbps, 212 kbps and 424kbps.

SOME DEVICES USING NFC TECHNOLOGY

CONCLUSION

Mobile handsets are the primary target for NFC and soon NFC will be implemented in most handheld devices.

The advancements in mobile wireless technology and communication standards have enabled usage of contactless and NFC based payment models.
